What is AMiga OS 4.1 based on?
« on: August 13, 2009, 04:13:36 PM »
Just a curiosity question about Amiga OS 4.1.  I thought all the source code to Amiga OS disappeared in the bankruptcy/insolvency movements of it's owners. What is the kernel that Amiga OS 4.1 is based on?  Is it using the same kernel as Morphos (Quark)?  Or the AROS kernel?

Is it using AROS code?

It's based on AmigaOS4.0! :-)

What it's based on is is the OS3.1 sourcecode and whatever OS3.9 sourecode Amiga managed to scrap together for Hyperion.

It isn't the MorphOS kernel, otherwise there would be no red team and big team competing to be The Sorest Looser. :-D

And AROS? Are you serious? Hehe. LOL! :-D   In this case it would be an Amiga inspired kernel, but not The Amiga kernel. And you would see no OS4 on x86 threads. I regret saying that "phrase" but it was a logical progression.

OS 4.1 is based on 3.1 sourcecode and 3.9 sourcecode but with a new replacement ExecNG which was developed by the Frieden brothers.  This replaces the older Exec with a more modern/scalable implemetation.

I wonder how much 3.5/3.9 code they did manage to re-use given all the legal issues with H&P; I know that Amidock is a completely new application, for example, but I'm guessing they somehow managed to get the code for things like ReAction...

A lot of the team that contributed to 3.9, also work on 4.1

According to the Friedens, very little of the original 3.1 source code was usable (search ann.lu for the quotes). Which would make sense given that it was all 68k asm.

Don't comment on things you don't understand. AROS is not Amiga inspired, it is an AmigaOS clone. You imply that AROS is a modern kernel, made to look like AmigaOS it isn't. Bear in mind that MorphOS used AROS code, and there has been quite a bit of code sharing between the projects.

Uhh.. except for all the C code. Which required 3 different C compilers in its original state :-)

They ditched Exec, and ditched large chunks of some other modules, but the code was not as useless as you imply.

And almost all the C stuff was from 3.5 and 3.9.. I was talking about 3.1 (as I stated in my original post).

Not useless, but only a little more useful than the RKMS... And contrary to what some people think, OS4.x is as new as MorphOS and AROS, these people should think about that before they make comments.

Could you please refrain from making assumptions?  I do recall hearing that Amiga Inc has no source code.  And thats from unofficial contacts.  I could be wrong as this was 4 years ago.

OS4/4.1 is based indeed on source code from os3.1/3.9.  But it came from another source, not A Inc.

 AROS is not Amiga inspired


Do you mean to say it wasn't "Amiga Inc." inspired? Certainly its inspired by the AmigaOS
